Tissue culture and plantlet regeneration of dwarf Prunus persica rootstock

Two explants of dwarf Yunong rootstock No.1 including stem segments and tips were cultured in vitro.The results showed that the suitable media for the bud induction from stem segments and tips were MS+6_BA 1.0 mg·L~(-1)+IBA 0.1 mg·L~(-1)+GA_3 1.0 mg·L~(-1) and MS+6_BA 0.2 mg·L~(-1)+IBA 0.01 mg·L~(-1)+GA_3 1.0 mg·L~(-1),and 1/2MS(+IBA) 1.0 mg·L~(-1)+IAA 1.5 mg·L~(-1) was the optimum medium of the rooting from shootings, the regenerated plantlets wene obtained in this experiment. These results might provide references for the quick propagation of dwarf Yunong rootstock No.1.
